Patent GB-901270-A (GB)
Title: Improvements in or relating to control systems for a press
Inventor: WISTREICH JOHN
IPC: B30B15/18
Filed: 1959-05-27
Abstract: 901,270. Forging presses. BRITISH IRON & STEEL RESEARCH ASSOCIATION. Aug. 29, 1960 [May 27, 1959], No. 18048/59. Class 83 (4). [Also in Groups XXIX and XXXVIII] A control system for a press, particularly an hydraulic forging press, comprises means for causing the press tools 12, 25 to move to a predetermined separation related to the initial thickness of the workpiece. The press platen 13 carries a rack 14 driving a tacho-generator 20 and a pair of rotary potentiometers 22, 21. The output of potentiometer 21 is fed into a control circuit 31 of the kind described in Specification 874,908, where it is compared with the output of one or other pre-set potentiometers 26, 27 determining respectively through a change-over switch X, the bottom and top limits of the platen. Circuit 31 controls an hydraulic circuit 32 for the press. The output of potentiometer 22 is fed through a servo-amplifier 29 to the field of servomotor 35 whose armature winding 34 is controlled by a switch unit 33. During the approach stroke, the latter is closed and thus the servomotor 35 drives the sliding contact of potentiometer 36 which controls the voltage on the pre-set potentiometers 26, 27. The tacho-generator 20 passes a voltage, depending upon the platen speed, to a gate 40 and immediately the workpiece is engaged by the upper tool the speed is reduced and the gate passes a signal through rectifier 42 and switch 43 to a pulse generator 44 which acts through a binary unit to open switch 33. Thus potentiometer contact 36 is stopped at a position determined by the initial thickness of the workpiece and this fixes the output of potentiometers 26, 27 which thus controls the bottom and top stroke limits in dependance upon the initial thickness of the workpiece. Interlock 50 then opens switch 43 whereby the bottom and top limits remain unaltered during subsequent strokes on the same workpiece. When the latter is withdrawn from the press a photo-head 47 receives light from source 48 and emits a signal which closes both the switch 43 and the switch 33. Instead of the units 40, 44, 45, 33, a pressure-responsive switch in the hydraulic system may be used. The photo-head 47 may be replaced by a manuallyoperated switch.

Abstract: 647,348. Indicating synchronism of internal-combustion engines. ENGLISH ELECTRIC CO., Ltd. July 11 ,1947. No. 18414. [Class 7(iv)] [Also in Group XXXIII] Apparatus for indicating synchronism of a number of internal-combustion engines comprises an ignition testing apparatus of the kind defined below and switching means arranged to apply to such testing apparatus synchronizing impulses from the ignition system of a selected engine and signal impulses from any one of the remaining engines. The ignition testing apparatus is of the kind comprising a cathode ray oscilloscope the time base of which is intended to be synchronized with the complete ignition cycle of an internal combustion engine by means of impulses derived from a point in the secondary circuit of the ignition system of the engine while signal impulses are intended to be supplied to the oscilloscope from a point in the primary circuit of the ignition system so that Figures corresponding to complete ignition cycles are displayed on the oscilloscope. In the Figure, 19 represents the oscilloscope. Synchronizing impulses are supplied to it through a conductor 17 while signal impulses are supplied to it through a conductor 18. The numerals 1, 2, 3, 4 represent internal-combustion engines from the ignition systems of which synchronizing impulses are supplied through conductors 5, 6, 7, 8 and signal impulses through conductors 10, 11, 12, 13 to conjointly controlled selector switches 9, 14 respectively. When the arm 23 of a switch 21 engages a lower contact the apparatus 19 can be used to test the ignition of engines 1 to 4 in turn by conjoint operation of the selector switches 9, 14. To test the synchronizm of any two engines synchronizing impulses from one engine and signal impulses from the other engine are applied to the oscilloscope 19. By operation of selector switches 21 and 22 and 9 and 14 synchronizing impulses from any of the engines 1 to 4 can be supplied to the conductor 17 and signal impulses from any engine can be supplied to conductor 18. When the oscilloscope is being used normally to test the ignition system of any engine pulses are seen on the screen and these pulses are stationary in a horizontal plane when being used to test for synchronizm. If the engines are not running at the same speed the pulses appear to move across the screen in a direction depending on which engine is running faster. In another arrangement in place of the switches 21, 22 a single push button is provided by which the arm 15 of the selector switch 9 can be disconnected from the conductor 17 and connected to the lead 5 so that each engine in turn can be tested for synchronizm with the engine 1. The Specification refers to ignition testing apparatus connected or permanently installed in an aircraft. Specifications 563,502 and 619,635 are referred to.
